Title (EN) FINELY PARTICULATE COMPOSITE LATICES AND USE THEREOF IN SOLVENT-FREE PAINTS
(FR) LATEX COMPOSITES A TRES FINE GRANULOMETRIE - LEUR APPLICATION AUX PEINTURES SANS SOLVANTS
Abstract:
(EN) Finely particulate composite latices free of non-polymeric surfactants and solvents may be prepared by the radical polymerisation of mixtures of hydrophobic monomers, e.g., styrene and an acrylic ester in emulsion in a solution of a low molecular weight copolymer such as a styrene/maleic anhydride copolymer. Said latices have a wide variety of uses, e.g. in leather processing; paints and surface coatings for wood; paints and particularly solvent-free paints for concrete, cement, plaster, roof tiles and metals; overprint inks and varnishes; adhesives for floor tiling; cement and mortar admixtures; non-pigmented coatings for leather, wood, metals and plastics; and paper sizing agents.
(FR) On peut préparer des latex composites à très fine granulométrie, et ne comportant ni solvant ni tensioactif non polymérique, en soumettant à une polymérisation radicalaire des mélanges de monomères hydrophobes, par exemple de styrène et d'un ester acrylique en émulsion dans une solution de copolymère de faible masse moléculaire de type styrène/anhydride maléique. Nombreuses applications: traitement du cuir; peintures et lasures pour bois; peintures pour bétons, ciments, plâtres, tuiles, métaux, en particulier peintures sans solvant; encres et vernis de surimpression; adhésifs pour carrelages; adjuvants pour ciment et mortier; revêtements non pigmentés pour cuirs, bois, métaux et matières plastiques, agents de collage des papiers.
